if you open the IIS manager on your webserver you see an icon named mime types
click on this icon
then you see a table with extentions
for instance
.xml
.jpg
.txt
Hi :good: If you are using Microsoft IIS than go to the IIS manager. There you find MimeTypes add .ywl in the table. In the code you write landscape=http://ilparadisodeidelfini.it/portoferraio.ywl this had to be landscape=http://www.ilparadisodeidelfini.it/yowidget/landscapes/portoferraio/portoferra...
